  1. 1. POSSIBLE TIMING OF THE TRANSITION FROM PRE-INDUSTRIAL TO INDUSTRIAL CLIMATE IN THE CENTRAL TO NORTHERN OF SWEDEN, BASED ON PROXY DATA FROM TREE-RINGS

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Mika Falkensjö Oppenheim; [2022-09-28]
    Nyckelord :Tree-ring; maximum latewood density MXD ; Scandinavia; pre-industrial; industrial climate;

    Sammanfattning : Earth’s climate has varied through time, with orbital forcing as the most dominant force on the climate system the last million years, causing glacial-interglacial cycles. The last glacial period ended about 11.6 thousand years (kyr), ago and the last interglacial maximum around 6.5 kyr ago. LÄS MER

  3. 2. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanna Andersson; [2021]
    Nyckelord :geochemistry; loess; XRF; weathering; climate change; N-W France;

    Sammanfattning : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. LÄS MER

  4. 3. The Eemian Baltic Sea hydrography and paleoenvironment based on foraminiferal geochemistry

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Julia Chonewicz; [2020]
    Nyckelord :trace elements; benthic foraminifera; last interglacial; temperature reconstruction; geochemistry; Earth and Environmental Sciences;

    Sammanfattning : I den här masteruppsatsen undersöktes geokemin i kalkskalen av bottenlevande foraminiferer från Anholt (Kattegat), Ristinge (Bälthavet) och Obrzynowo (Egentliga Östersjön), för att rekonstruera de hydrografiska förhållanden i Östersjön och paleomiljön under den senaste interglacialen (130 - 115 ka BP). De variabler som analyserades innefattade Mg/Ca, Ba/Ca och Mn/Ca samt stabila syre- och kolisotoper (δ18O och δ13C) i kombination med data från tidigare studier och modern hydrografi. LÄS MER

  5. 4. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Pelle Kronborg; [2020]
    Nyckelord :loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

    Sammanfattning : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. LÄS MER

  7. 5. Size and Abundance of Late Pleistocene Reticulofenestrid Coccoliths from the Eastern Indian Ocean in Relation to Temperature and Aridity

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jeroen van Dijk; [2017]
    Nyckelord :coccoliths; abundance; biometry; circular polarized light microscopy; Late Pleistocene; Marine Isotope Stage 11; kokkoliter; mängder; biometri; cirkulär polariserat ljus; pleistocen; Marine Isotope Stage 11;

    Sammanfattning : Measurements on coccolith abundance and mass can be used as a signal of primary productivity and pelagic calcification in response to environmental change. The Leeuwin Current (LC) is known to transport warm and low-salinity waters from the Indo-Pacific Warm Pool (IPWP) southwards along the coast of West Australia. LÄS MER
